This monograph presents a view on grammaticalisation radically different from
standard views centering around the cline of grammaticality. Grammar is seen
as a complex sign system, and, as a consequence, grammatical change always
comprises semantic change. What unites morphology, topology (word order),
constructional syntax and other grammatical subsystems is their paradigmatic
organisation. The traditional concept of an inflexional paradigm is generalised as
the structuring principle of grammar. Grammatical change involves paradigmatic
restructuring, and in the process of grammatical change morphological,
topological and constructional paradigms often connect to form complex
paradigms. The book introduces the concept of "connecting grammaticalisation"
to describe the formation, restructuring and dismantling of such complex
paradigms. Drawing primarily on data from Germanic, Romance and Slavic
languages, the book offers both a broad general discussion of theoretical issues
(part one) and three case studies (part two).
